The matter involved corrupt customs officials, who not only failed to report the arrival of aircraft carrying millions of dollars in narco-profits, but actually assisted the smugglers in carrying the bags of money to their waiting automobiles. There have been rumours afoot for years about the massive amounts of cash coming into Panama through Albrook, which is a private aviation airport.
Reportedly, the cash courier flights, mainly from Mexico and Honduras, into the Republic of Panama, involved 47 trips. There were also indications that some of the flights originated in the Continental United States, which indicates that bulk cash smuggling out of CONUS is not being interdicted. Some flights with cash were coming in from Colombia as well.
* The official name is Aeropuerto Marcos A Gelabert; it is Panama's principal domestic airport.
